Meghan was understood to have flown back to Canada, where they had been staying in a mansion on Vancouver Island for several weeks. Harry stayed in the UK, but rejoined his wife after holding some meetings in London.

The couple revealed on Instagram in March that they had recently held meetings at Stanford University, close to California’s Silicon Valley.

Writing in a post about Meghan’s trip to the National Theatre, they added: “Recently, The Duke and Duchess of Sussex also visited Stanford University where part of their learning journey included a virtual reality presentation that allows the user to experience life through another person’s point of view.”

Meghan’s first job outside the role of senior royal was confirmed on Thursday, as Disneynature announced she was the narrator on a film called Elephant, to be streamed on Disney+.

A trailer for Elephant, posted on the official Disney Twitter account, revealed that it “follows one family’s extraordinary 1,000 mile journey across Africa on an adventure that will change their lives”.

It’s thought she did the voiceover in London last Autumn.

Prince Harry released the single for the Invictus Games on Friday, despite the games being moved to next year because of the coronavirus outbreak.

Adding a picture to their Instagram story, Harry said: “Thank you for the support, Jon.

“Well done to the choir, sounds great.”

Meghan and Harry may have hinted they were no longer in Canada on Thursday night, when their post for the Clap for Carers initiative was written from “across the pond” rather than naming a specific country.

After announcing their intention to step back from life as senior royals, Harry told supporters at a Sentebale dinner that he “had no other option” but to make the move.

He said: “The decision that I have made for my wife and I to step back, is not one I made lightly. It was so many months of talks after so many years of challenges.

“And I know I haven’t always gotten it right, but as far as this goes, there really was no other option.”

He thanked charity supporters for watching out for him but added “the media is a powerful force” as he promised to live a life of service.
